CORKSCREW.

SPECIFICATION forming part of Letters Patent No. 300,936, dated June 24,1884.

Application filed December 1, 1883.

' To all whom, it may concern:

Be it known that I, WILLIAM E. ALVORD, of Appleton, Outagamie county,\Visconsin, have invented a new and Improved Corkscrew, of which thefollowing is a full, clear, and exact description.

The object of my invention is to provide a new and improved corkscrew,which is so constructed that the cork can be extracted without requiringthe operator to pull on the corkscrew.

The invention consists in a corkscrew formed on the lower end of a rodcontained in an externally-threaded tube, which in turn is contained inan internally-threaded tube. The

rod on which the corkscrew is formed is pro- 7 vided with an annularridge, forming a shoulder, and with a handle, and the exterior tube isprovided with longitudinal ridges for holding it so that it cannot slipin the hand.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures. Figure l is a longitudinalelevation of my improved corkscrew. Fig. 2 is a longitudinal sectionalelevation of the same, showing how it is used, Fig. 3 is a sectionalplan view of the same on the line :0 m, Fig. 1. Fig. 4 is alongitudinalview of the externally-threaded tube.

A corkscrew, A, is formed on the lower end of a smooth round rod, B,provided at its upper end with a cross-handle, G, and a short distancebelow the handle with an annular ridge, D,forming a shoulder. The rod Bpasses loosely through the smooth bore of a tube, E, flared out at itslower end to form a socket, F, adapted to receive the cork G. The tube Eis provided on its exterior with a righthand screw-thread, adapted toengage with a corresponding screw-thread formed on the inner surface ofa tube, H, provided on its outside with an enlargement, J, havingvertical ribs 11. The tube E is placed on the bottle in such a mannerthat the cork G passes into a socket, F, and then the rod B is turned bymeans of the handle in such a manner that the corkscrew passes into thecork. The

(No model.)

handle of the corkscrew is then held to prevent it from turning, and thetube H is turned from right to left, whereby the said tube H will bescrewed upward on the tube E, and will force upward the rod B by actingon its shoulder, thereby extracting the cork from the bottle.

The rod B can be withdrawn from the tube E, and the corkscrew can thenbe used in the usual manner.

The ridges a permit grasping the tube Hin such a manner that it will notslip in the hand.

I am aware that it is old to form a corkscrew of a smooth rod having atits upper end a handle and a lug, and at its lower end a screw, and tosurround said rod with an externally screw-threaded tube having anannular flange at its lower end and a notched flange at its upper end,said tube being surrounded by a tube having internal screwthreads at itsupper end, whereby upon rotating the corkscrew-rod its lug will engagethe notched flange on the externally-threaded tube, causing said tube tobe raised, thereby forcing the corkscrew upward and withdrawing thecork.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1 1. In a corkscrew, the combination, witha rod, B,having a corkscrew formed on its lower end, and provided with an annularridge, forming a shoulder, of the externally-threaded tuloe E, having asocket, F, formed on its lower end, and of the internally-threaded tubeH, surrounding the tube E, substantially as herein shown and described.

2. In a corkscrew, the combination, with a rod, B, having a corkscrewformed on its lower end, and provided with an annular ridge, forming ashoulder, of the externally-threaded tube E, having a socket, F, 011 itslower end, and the internally threaded tube H, surrounding the tube E,and provided with ribs a, substantially as herein shown and described.

WVILLIAM E. ALVORD.
